Thanks to the overwhelming evidence from astrophysics, cosmology and neutrino oscillation experiments, it is well established that the new physics beyond Standard Model (SM) is needed to accommodate two missing spices: tiny but nonzero neutrino masses and dark matter (DM). The scotogenic model, originally proposed by by Krauss et al[1]} and Ma[2]}, is one of the appealing ways to explain the above two issues simultaneously, where the small neutrino masses arise only at loop level and
DM plays a role of mediated field propagating inside the loop diagram. For a review on various interesting realizations, see Ref. [3]}.
